Abstract

See full text

The present invention provides a process for the preparation of metal-doped zeolites comprising the steps of

    i) provision of a dry mixture of a) a zeolite,b) a compound of a catalytically active metal, ii) intimate grinding of the mixture,iii) heating of the mixture in a reactor,iv) cooling to room temperature and obtaining the metal-doped zeolite,wherein the internal pressure in the reactor during the heating is kept in a pressure range from 0 to −200 millibar.
